Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

From Fisheries to the Basketball Court

For most of the 20th century, the world’s fisheries provided a classic example of what ecologist Garrett Hardin famously called “the tragedy of the commons.” As Hardin explained, each person can capture the full benefit of a resource, while the “overgrazing” costs are shared among all users. As a result, individuals lack the incentive to exercise restraint, which leads to overconsumption. In order to combat this phenomenon, Jonathan H. Adler, a professor at the Case Western University School of Law and a senior fellow at the Property and Environment Research Center, and Nathaniel Stewart, an attorney in Washington, D.C., argue for utilizing territorial or catch-share allocation among fishery participants. They make the case that property-based management aligns fisher incentives with the underlying health of the resource and appears to reduce the adverse environmental effects of commercial fishing. “There is ample empirical evidence that such institutional reforms encourage more efficient fishery exploitation, reduce overcapitalization, and eliminate the dreaded ‘race to fish’ — the wasteful and dangerous effort to catch as many fish as possible in a very short season,” Adler and Stewart write.

Is America’s housing finance crisis finally behind us? According to Charles W. Calomiris, professor of financial institutions at Columbia Business School, and Stephen H. Haber, professor of political science at Stanford University, the main source of potential trouble — risky investments in residential mortgages, undertaken by overleveraged government-sponsored enterprises and banks — has not been addressed. The authors review the latest round of policies, from the implementation of the Volcker Rule to the creation of the Financial Stability Oversight Council. “The sad truth is that reforms that have been implemented are either irrelevant or have been lobbied to the point that they have been made irrelevant,” they write. In short, there is little indication that the Obama administration is serious about rolling back mortgage-risk subsidies. “Until average Americans decide to punish political leaders for acquiescing to the subsidization of mortgage risk, effective reform will remain elusive, although reform likely will be promised again — right after the next banking crisis,” Calomiris and Haber conclude.

Next, Ike Brannon, a senior fellow at the George W. Bush Institute, examines the forces that have increased income inequality in the United States by considering how they affected one particular market: professional basketball. The National Basketball Association’s (NBA) explosion in popularity has created a few spectacularly rich people, but most of the wealth created has gone to people who hold solidly middle-class jobs. This has not only produced entertainment value for hundreds of millions of fans, but has created tens of thousands of well-paying jobs that don’t involve shooting a jump shot. “That the result of this has also been the creation of a few dozen millionaires each year is a good problem to have,” Brannon writes. Taxing a majority of their wealth away, he argues, would accomplish little in terms of our long-term budget situation and, if done poorly, could easily punish the nonrich, as well as threaten the league’s future success. “That’s a lesson that holds for the rest of the economy as well.”

Since most economic controls over domestic commercial aviation ended in the late 1970s, the airline industry has changed dramatically. The underlying philosophy has been that competition, while not perfect, was generally preferable to government dictates. Kenneth Button, a professor of public policy at George Mason University, explores whether competition can be taken further, and in particular whether market entry can be widened. “While the 1978 Airline Deregulation Act removed many of the legal barriers that limited the routes that individual carriers could serve and the fares they could set, it did nothing to open up the domestic market to international carriers,” he writes.
